* reapply 112894:Chris Lattner2010-09-02
| | | | | | | | | | | | | | | | | | Remove #uses comments from functions: they we're padded out to column 50 and were potentially confusing for externally visible functions. going further, remove the "<i8**> [#uses=3]" comments entirely. They add a lot of noise, confuse people about what the IR is, and don't add any particular value. When the types are long it makes it really really hard to read IR. If someone is interested in this sort of thing, the right way to do this is to implement an AsmAnnotationWriter that produces the same output, and add a flag to llvm-dis (only) to produce this output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112899 91177308-0d34-0410-b5e6-96231b3b80d8

* For ARM stack frames that utilize variable sized objects and have eitherJim Grosbach2010-09-02
| | | | | | | | | | | | | | | | | large local stack areas or require dynamic stack realignment, allocate a base register via which to access the local frame. This allows efficient access to frame indices not accessible via the FP (either due to being out of range or due to dynamic realignment) or the SP (due to variable sized object allocation). In particular, this greatly improves efficiency of access to spill slots in Thumb functions which contain VLAs. rdar://7352504 rdar://8374540 rdar://8355680 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112883 91177308-0d34-0410-b5e6-96231b3b80d8
* - Change __builtin_ia32_palignr intrinsic type to match the pattern in clang.Bill Wendling2010-09-02
| | | | | | | | | | | | | | | - Add patterns to match the following MMX builtins: * __builtin_ia32_vec_init_v8qi * __builtin_ia32_vec_init_v4hi * __builtin_ia32_vec_init_v2si * __builtin_ia32_vec_ext_v2si These builtins do not correspond to a single MMX instruction.

| | | | | | | | | | | there are clearly no stores between the load and the store. This fixes this miscompile reported as PR7833.
